Fully Bayesian binary Markov random field models: Prior specification and posterior simulation
We propose a flexible prior model for the parameters of a binary Markov random field (MRF) defined on a rectangular lattice and with k ×l cliques. The prior model allows higher-order interactions to be included in the MRF. We also define a reversible jump Markov chain Monte Carlo (RJMCMC) algorithm to sample from the associated posterior distribution. The number of possible parameters for an MR...
متن کاملTotal Variation Minimization and a Class of Binary MRF Models
We observe that there is a strong connection between a whole class of simple binary MRF models and the Rudin-Osher-Fatemi Total Variation minimization approach to image denoising. This leads to new algorithms. We then compare the e ciency of various algorithms.
متن کاملSuperpixelizing Binary MRF for Image Labeling Problems
Superpixels have become prevalent in computer vision. They have been used to achieve satisfactory performance at a significantly smaller computational cost for various tasks. People have also combined superpixels with Markov random field (MRF) models. However, it often takes additional effort to formulate MRF on superpixellevel, and to the best of our knowledge there exists no principled approa...
متن کاملMarkov Models for Image Labeling
Markov random field MRF is a widely used probabilistic model for expressing interaction of different events. One of the most successful applications is to solve image labeling problems in computer vision. This paper provides a survey of recent advances in this field. We give the background, basic concepts, and fundamental formulation of MRF. Two distinct kinds of discrete optimization methods, ...
متن کاملBayesian Determination of Sample Size in Longitudinal Studies with Binary Responses Using Random Effects Models
Sample size determination is important in all statistical studies including longitudinal studies. This is usually done by considering a target power to reduce the costs of sampling. Choosing the right sample size using efficient methods, ensures that the researcher achieve goal of the study, by spending the least amount of energy, time and money. In this article, using a method based on simulat...
